Battery in Trunk Wiring That Exceeds NHRA Requirements

Please PM me regarding this.
I was posting on another thread regarding this subject, and I am now completely confused.
Specifically, the subject is to put a battery in the trunk, wire in a cut off switch and do it in a way where there’s no hot wires going to the front of the car other than when it is starting. All for the purpose of being race track legal. NHRA (for one) will accept it being wired with wires being hot all the time. This could be dangerous if a wire becomes shorted. NHRA doesn’t care about your car, they just want it to shut off when their personnel throws the switch.
I’m not good with solenoids, relays, continuous duty relays, maxi fuses, fusible links, etc. However, I am good at making safe, sound connections.
I want to ask a big favor of someone. I need specifics as to what wire to hook up to what connection on what solenoid or relay, etc. This thread has what I’m trying to accomplish: questions about battery disconnect wiring
I think a well thought out reply would be a tremendous attribute to FABO. I’ve never seen a post or thread that is completely clear and concise. (I’m sure these posts are clear to you folks who know what you’re doing, but lots of us are not as sure.)
I have everything in that thread. As an example of what details are needed: Please describe what wires go where on the continuous duty relay, and please be careful to distinguish between specific relays, solenoids, etc.
If someone would want to come to my garage and show me, I would pay you and write the process up for FABO. I think as an amateur electrician, I could write it so other amateurs could understand. With all due respect to you professionals, it’s hard for you to see how simple a lot of us need it to be!
Again, please PM me.
